# Optoelectronics vs Learn SEO

The clearest difference is iOS requirement: Learn SEO at 12.0 against Optoelectronics's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Optoelectronics sells 6 in-app purchases, starting at $9.99 per month and Learn SEO sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
